This product is specifically designed for the front chassis system of the BYD Qin PLUS EV. It is a core load-bearing structural component located beneath the electric motor, connecting the body to the suspension system—the front subframe assembly. Named for its resemblance to the traditional Chinese "Yuanbao" (ingot), the front subframe is a critical component of the chassis system, serving multiple functions: supporting the electric motor and reducer, carrying the suspension and steering systems, absorbing road impact loads, and enhancing overall vehicle rigidity and stability.
As a core sales model of BYD's pure electric vehicle lineup, the BYD Qin PLUS EV is available in multiple range versions including 420KM, 510KM, and 610KM. Due to the heavy weight and low center of gravity of the battery pack, pure electric vehicles place higher demands on the load-bearing capacity and structural rigidity of the subframe. The Qin PLUS EV features a non-full-frame front subframe, with a MacPherson independent front suspension, where key components such as the lower control arm and steering tie rod are made of steel. The subframe is connected to the body via raised brackets to create space for the battery pack.
The main functions of the front subframe include: supporting the electric motor and reducer; when the vehicle travels over rough roads, impact forces from the wheels are transmitted through the lower control arms to the subframe, which distributes the load evenly to the body side rails to prevent stress concentration; during low-speed collisions, the subframe deforms controllably through its预设structure to absorb impact energy, protecting the traction battery from direct impact.
As a professional manufacturer of automotive chassis structural parts, we develop and produce strictly according to BYD OEM technical standards. Using high-strength steel stamping and welding, with key stress areas optimized through finite element analysis (FEA) and an e-coat anti-corrosion finish, the product passes rigorous salt spray tests and dimensional accuracy inspections. The mounting holes are 100% precisely matched with the original vehicle for direct replacement of accident-damaged or severely corroded original subframe assemblies, restoring chassis structural rigidity and driving stability.
